Regardless. Burning any kind of fossil fuel to produce electricity is
expensive and results in people having to pay high electric bills.
Eventually, when electric cars become common, people are going to find
out how much hydroelectric power potential Manitoba has.
There is a electricity producing station in East Selkirk, Manitoba that
uses either coal or natural gas to produce electricity. Manitoba Hydro
only runs that facility when they need additional power during peak
demand periods, or so we're being told. I grew up in West Selkirk
(across the Red River from East Selkirk), and we could see the smoke
stacks of that electrical generating station from West Selkirk, and I
never remember seeing smoke come out of those stacks. All of our
electrical needs come from falling water, which is free.

It's nice that it works for you, because you have to appropriate
natural resources. It's not like the USA has hundreds of reasonable
hydro sites that could be developed. And any that can be, I can assure
you the hippies will be there blocking those because of the environmental
impact. Damming up rivers, creating huge artificial lakes have environmental
We have electric dryer and the lightest month last year was about 600
KWH. Gas is not available here, but we use propane to cook oil to
heat. We do use AC in the summer though and that would be expensive.
Gas AC used to be decent, but I don't even know if residential units
are still practical..

It starts with: "Hey kids ~ want to have less pH bounce, shinier,
silkier water with no algae problems? But wait, there's more! You'll
also be using half as much chlorine as you do now! Hard to believe?"
Basically you have choice of a pre-mixed solution that is ph neutral or
buying borate and acid and adding them alternately to keep the ph from
Don't any of you folks have Time of Day Rates? My off-peak rate here
is about half the on-peak rate in the summer. Winter there isn't much
difference. So I run my pool in the off-peak hours and keep the AC
set higher in the on-peak and then turn it down after 8 at night till
1 in the afternoon the next day when the on-peak hits again.
They offer the option of Time-of-Use service but the peak rates under
that rate plan are higher than the single-rate plan rates.
"Sunlight is the biggest consumer of chlorine, so the pool needs to be
circulating when the sun is shining down on the pool. That way the
chlorine is constantly moving around the pool."
The mistake many people make is to think that the sole reason to run the
pump is to filter the water. It's not. The bigger reason is to keep the
chlorine (or other sanitizer) circulating through the pool.
Unfortunately, the problem with a pool is that you must run the pump
during the day, preferably at the hottest part of the day. There's
little reason to run the pump at night unless you're doing something
like an algae clean-up where the reason you're running the pump is
solely to filter the water. A compromise would be to run it four hours
in the morning before the peak rate kicks in at 1:00 p.m., then run it
another 4 hours during the hot part of the day.
My neighbor has solar on his house and he generates enough electricity
that his electricity bill is $0 even though he runs the pool pump at the
proper time of day. You don't get money back for generating more
electricity than you use.
The bottom line is that since the pool pump must be operating during
peak rate time it's worse to be on the peak rate plan if you have a
pool. It would cost 48-52¢ per KWH where I am.
The way to reduce the total cost is to:
a) circulate the same amount of water with less electricity. A lower
speed pump run at half speed for twice as long pumps the same amount of
water for about 75% of the electricity, and a variable speed pump saves
even more electricity. See < http://www.youtube.com/watch?vMIz4R-1d2k .
b) reduce the amount of water that needs to be circulated. You can do
this by reducing the amount of sun hitting the water (with a pool
cover), or by using chemicals that reduce the need to circulate the water.

Logically, I don't see why you would not want to do exactly the opposite.
Why circulate the chlorine so the sun can destroy more of it? If the
sun diminishes the chlorine in the top few inches, so what? In eight
hours, the pump comes on and mixes it up again. The exception would
be times when you have people using the pool, but when it's unoccupied
it seems to me the better strategy is to filter at night. I've done it
both ways and never noticed any difference.
Actually per the video, by cutting the flow rate in half, you only
use 35% of the electricity. That's a huge savings. If you cut the flow
rate to 1/4, you use only 17% of the electricity to move the same
amount of water. BTW, good video find.
The fancy $1000 motor saves 17%, at the full 80GPM rate. Not clear
how much it saves at the lower speeds. Also, with regard to the fancy
motor, he compared it to a standard motor of unknown vintage. Even
newer regular motors are somewhat more efficient. I just bought an
Emerson dual speed that is rated as being an energy efficient design.
I don't think it's going to make that 17% difference, but I would hope
that it's maybe 5% or so better than a 15 year old motor.
The question with the fancy variable speed pumps is if they are
worth the huge additional ~$1000 upfront cost. Here where we only
have a 3 month season and electric is .18 kwh, I think the answer is
no. But with .36 kwh rates and a long season, getting one of those
and running it at 1/4 speed might have a reasonable payback period.
I wonder if anyone makes motors that are 1/4 speed that you could
swap out with an existing pump? IDK how well that would work. If
the old motor was moving 80 gpm and you put in a 1/4 speed motor,
would it move 20 gpm? Maybe not. I think these variable speed
pumps have some sensing whereby they adjust the motor speed to get
the desired flow rate. The big negative I see with those is that
they cost $1000+, they are loaded with electronics, they are in a
somewhat hostile environment, could get damaged by a surge, etc and
if they do a couple years in, you're out $1000. With my $190 dual
speed, no such worries. That's why for me, no way they were worth
the big additional cost.
and a variable speed pump saves

I was wondering that too for our friends in CA. You would think with the
super progressive rate structure they would have some lower rate at night.
But maybe they have no smart metering.
That rate structure in CA reminds me of the income tax. The hippies pass
these laws claiming it won't affect most people, just those that are
running AC with the windows open or living in a 20,000 sq ft house.
Then before long, you have rates that screw guys like SMS.
Same thing with the income tax. When it was
passed it only applied to incomes that would be the equivalent of $10mil+
today and it was just a couple of percent. Within a decade it applied
to most people and the rate had skyrocketed, eventually reaching 90%.
We have it if you choose the electric company as your supplier, but I
don't see any big bargain for most of us. Peak time is Noon to 8 PM
Mon - Fri. The generation rate is. 11.86¢ for peak and 8.36¢ off
peak. With another supplier, I pay 7.95¢ at any time. These are
generation rates only. Add 8.6¢ for delivery.
If the other suppliers stated to offer it, then savings may happen.
